Which part of the model shows carbon moving from the biosphere to the
atmosphere?

A. Decomposers breaking down the material

Explanation:

Decomposition is the process in which decomposers such as bacteria break down the organic material in the atmosphere.

In the given image, decomposers breaking down the material shows carbon moving from the biosphere to the  atmosphere because decomposers break down the dead organisms and in the process the carbon in the bodies of dead organism get back in to the atmosphere.

Hence, the correct answer is "A. Decomposers breaking down the material".

sorry to break it to ya but no one can answer your question it's just

jk but i am serious about the part that most people cant answer it beacuse you did not mention the section you are talking about. but it would if you added some detail and were a bit more specific.
